Air quality monitoring for landfills and waste treatment sites
Landfills and waste treatment operations can create changing environmental conditions linked to waste handling, decomposition, vehicle movements and treatment activities. Aernode provides continuous monitoring across operational areas and site boundaries, giving operators structured data to review changes in relevant environmental parameters, relate measurements to site activity and meteorology, investigate reported events and support day-to-day environmental management.
Continuous insight for proactive environmental management
Environmental conditions around landfills and waste treatment facilities can vary with waste composition, handling activities, decomposition processes, vehicle movements and meteorological conditions. Continuous monitoring provides a persistent record of relevant environmental parameters, helping operators review changing conditions and identify recurring patterns across operational areas and site boundaries.
With monitoring nodes positioned around relevant activities, perimeter areas and nearby receptors, measurements can be reviewed alongside site operations and local meteorology to provide additional context for particulate or gaseous variations and reported odour episodes. The resulting data supports operational review, mitigation planning and documented communication with external stakeholders.
Operational value of continuous monitoring for waste sites
Continuous environmental data gives operators additional context to review changing conditions, investigate reported events and support day-to-day environmental management across landfills and waste treatment facilities.
Continuous environmental oversight
A distributed network provides an ongoing record of selected environmental parameters across operational areas and site boundaries, helping operators review variations that periodic measurements may not capture.
Better context for reported odour events
Measurements can be reviewed alongside waste handling activities, operating conditions and meteorological data to provide additional context when odour episodes are reported and support a more informed assessment of the circumstances surrounding the event.
Active monitoring with configurable alerts
Configurable thresholds can highlight changes in monitored parameters, giving operators an additional signal to review activities, environmental conditions or meteorology in relevant areas of the site.
Identify recurring environmental patterns
Comparing measurements across operating areas, time periods and meteorological conditions can help reveal recurring patterns and support more targeted review of activities or locations requiring further attention.
Structured data for reporting and communication
Consistent time-series records support internal environmental reviews, documented follow-up of reported events and evidence-based communication with municipalities, neighbouring communities and other stakeholders.
A monitoring network designed around waste operations and site boundaries
Each deployment is configured around relevant operational areas, site boundaries, prevailing winds and nearby receptors, so measurements provide useful context for day-to-day environmental management and the review of changing conditions or reported events.
Define the monitoring objectives
Identify the operational areas, site boundaries and nearby receptors most relevant to the monitoring programme, considering waste handling, treatment activities, active landfill areas and the environmental issues the network should help review.
Configure and position the network
Select the relevant environmental parameters and position monitoring nodes around waste handling or treatment areas, landfill zones and perimeter locations, taking prevailing winds and nearby receptors into account.
Establish the operational workflow
Connect measurements with dashboards, configurable alerts, meteorological data and reporting outputs so operators can review changing conditions, investigate reported events and maintain a structured environmental record over time.
Parameters commonly monitored around landfills and waste treatment sites
| Parameter | Why it matters at landfills and waste treatment sites |
|---|---|
|
PM₂.₅ / PM₁₀
Particulate matter
|
Waste handling, crushing or screening operations, vehicle movements, unpaved roads and exposed material can contribute to local particulate levels. Distributed PM monitoring helps review dust variations across operational areas and at the site boundary. |
|
H₂S
Hydrogen sulphide
|
Hydrogen sulphide may be associated with decomposition of sulphur-containing organic material and selected waste streams. Monitoring can help review concentration trends and provide additional environmental context when odour episodes are reported. |
|
NH₃
Ammonia
|
Ammonia can be relevant for waste streams containing nitrogen-rich organic material and around selected biological treatment or storage areas. Measurements provide additional information for reviewing variations between operating periods and site activities. |
|
VOCs
Volatile organic compounds
|
Volatile compounds may originate from mixed waste streams, decomposition, storage or treatment activities. VOC monitoring can provide a broad indicator of changing volatile conditions and useful context for the review of recurring or reported events. |
|
Wind
Speed and direction
|
Wind speed and direction provide essential context for interpreting measurements across the site and its perimeter, particularly when reviewing variations observed at different monitoring locations or conditions reported near surrounding receptors. |
Monitoring configurations are project-specific; particulate matter, H₂S, NH₃, VOC indicators and meteorological parameters are selected according to waste streams, site activities, facility type and monitoring objectives.

Frequently asked
questions
Practical answers on landfill air monitoring, odour-related conditions, dust, network design and continuous environmental monitoring across waste treatment sites.
What types of landfills and waste treatment sites can benefit from continuous air quality monitoring?
Continuous ambient monitoring can be useful at facilities where waste handling, decomposition, treatment processes or vehicle movements create changing dust, gaseous or odour-related conditions that are difficult to characterise through occasional measurements alone.
Typical applications include municipal solid waste landfills, construction and demolition waste landfills, waste transfer stations, materials recovery and recycling facilities, composting and other biological waste-treatment sites, mechanical-biological treatment plants, and facilities with screening, crushing, stockpiling or other intensive material-handling operations.
The monitoring strategy should be adapted to the actual waste streams, processes, site layout and nearby receptors rather than applying the same sensor configuration to every facility. Aernode monitoring stations can be deployed as single-site or distributed multi-node networks across operational areas and site boundaries.
Which pollutants and environmental parameters are commonly monitored around landfills and waste treatment sites?
There is no single pollutant package for every waste site. The appropriate parameters depend on the waste streams, treatment activities, potential emission sources and monitoring objectives.
Common ambient monitoring targets include particulate matter PM₁₀ and PM₂.₅ where dust is generated by traffic, handling, crushing or exposed material; H₂S where sulphur-containing waste or decomposition may contribute to odour-related episodes; NH₃ around selected nitrogen-rich or biological waste streams; and VOC indicators where volatile compounds may be released from mixed waste, storage or treatment activities.
Wind speed and direction are also important for interpreting concentration changes across a site and its boundary. Aernode Sensor Kits allow different pollutant combinations to be configured according to the facility type and project requirements.
How can continuous air monitoring help investigate odour complaints at landfill and waste treatment sites?
Continuous monitoring creates a time-resolved environmental record that can be reviewed when an odour complaint or reported event occurs. Operators can compare the time and location of the report with H₂S, VOC or other relevant indicator trends, wind direction, measurements from different monitoring nodes and site activities taking place at the time.
Chemical sensors do not measure human odour perception directly, and a single marker such as H₂S cannot represent every landfill or waste-site odour.
The value of the network is therefore to provide objective environmental context, identify recurring patterns and help determine where operational review or more targeted investigation should be focused.
Aernode Cloud and Reporting Tools can preserve the monitoring history and support event review, alerts and structured follow-up records.
How should an ambient monitoring network be designed around a landfill or waste treatment site?
There is no fixed number or universal layout of monitoring stations. Network design should start from the monitoring objective and consider site geometry, active emission areas, prevailing and variable wind directions, site boundaries, nearby sensitive receptors and the need for representative background or upwind measurements.
Relevant locations can include active landfill cells, waste reception and tipping areas, screening or crushing operations, internal roads, stockpiles, composting or biological-treatment areas, selected site-boundary locations and positions downwind of activities of interest.
A multi-node network makes it possible to compare conditions across operational areas rather than relying on one measurement point. Meteorological measurements, particularly wind speed and direction, are an important part of interpreting a distributed ambient monitoring network.
Aernode Accessories include meteorological and deployment options that can be selected according to the monitoring strategy.
How can continuous particulate monitoring support dust management at waste sites?
Dust and particulate levels can change quickly with vehicle movements, unpaved roads, loading and unloading, crushing or screening, stockpile handling, exposed material and dry or windy weather.
Continuous PM₁₀ and PM₂.₅ monitoring can show when these variations occur and whether they are concentrated in operational areas or are also observed at the site boundary.
This information can support trigger-based operational review, comparison of conditions before and after mitigation measures, and documentation of recurring dust patterns. Where appropriate, alerts can be configured to prompt operators to review activities or dust-control measures when monitored values change.
Continuous PM monitoring is not a substitute for dust-deposition, bioaerosol or other permit-specific monitoring methods where those are required. It provides an additional high-frequency ambient dataset for day-to-day environmental management.
Can continuous monitoring support an Odour Management Plan or emissions management plan?
Yes. Continuous ambient measurements can add an objective time-series record to an Odour Management Plan or wider emissions-management workflow.
Data can be reviewed alongside waste inputs, operational activities, mitigation measures, complaint records and meteorological conditions to help document when recurring or unusual conditions occur.
The network can also support configurable alerts, event follow-up and review of whether changes in operating practice are associated with changes in monitored conditions.
This information complements, rather than replaces, site inspections, sensory odour assessment, olfactometry or other monitoring and assessment methods required by the environmental permit.
Aernode Reporting Tools can be configured for historical analysis, scheduled outputs and stakeholder-facing reporting where these functions are required by the project.
Is ambient perimeter air monitoring the same as formal landfill-gas monitoring?
No. These are different monitoring objectives and should not be treated as interchangeable.
Formal landfill-gas monitoring can involve dedicated measurements within the waste mass, gas-collection infrastructure, perimeter or subsurface boreholes, landfill-surface emission surveys and monitoring of gas-treatment equipment.
Ambient perimeter air monitoring instead measures outdoor air conditions around operational areas, the site boundary or nearby receptors. Depending on the project, it can include particulate matter, H₂S, NH₃, VOC indicators and meteorological parameters.
Aernode is designed for continuous indicative and supplementary ambient monitoring. It should not be presented as a replacement for statutory landfill-gas migration, surface-emission or other dedicated compliance-monitoring methods where these are required.
